A-0 (or A0) is a programming language for the UNIVAC I and UNIVAC II , using three-address code instructions for solving mathematical problems. A-0 was the first language for which a compiler was developed.
A-0 was produced by Grace Hopper's team at Remington Rand in 1952. Later internal versions were A-1 , A-2 , A-3 (released as ARITH-MATIC) and AT-3 (released as MATH-MATIC).
